CBCGPChartLegendCtrl

Detailed Description

The CBCGPChartLegendCtrl implements the functionality of a visual control (CBCGPVisualCtrl) that hosts a CBCGPChartLegendVisualObject.

You can use this control to place an advanced legend on a dialog or embed it into a dockable pane.

The following code illustrates how to embed a legend into dockable pane:

Copy
class CMyDockingPane : public CBCGPDockingControlBar
{
public:
CMyDockingPane();
// Attributes
public:
// other code.....
afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
afx_msg void OnSize(UINT nType, int cx, int cy);
AFX_MSG DECLARE_MESSAGE_MAP()
};
int CMyDockingPane::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CBCGPDockingControlBar::OnCreate(lpCreateStruct) == -1)
return -1;
// note that rectangle must not be empty
m_legend.Create(CRect(0, 0, 1, 1), this, 0);
return 0;
}
void CMyDockingPane::OnSize(UINT nType, int cx, int cy)
{
CBCGPDockingControlBar::OnSize(nType, cx, cy);
// Legend control should cover a whole client area:
m_legend.SetWindowPos (NULL, -1, -1, cx, cy, SWP_NOMOVE | SWP_NOACTIVATE | SWP_NOZORDER);
